PGBD1（piggyBac transposable element derived 1），癌症关联基因，基因ID：84547，在不同的动物中发现的猪瘟蛋白家族是与飞蛾典型的猪瘟转座子（trichoplusia ni）的转座子相关的转座子。这个家族还包括一些基因组中的基因，包括人类，这些基因似乎是从猪的转座子中获得的。该基因属于猪瘟转座因子衍生（pgbd）基因的亚家族。PGBD蛋白似乎是新的，与其他转座酶或其他已知蛋白家族没有明显关系这种基因产物在大脑中有特异性表达，但其确切功能尚不清楚。选择性剪接导致编码相同蛋白质的多个转录变体。[由RefSeq提供，2010年5月]The piggyBac family of proteins， found in diverse animals， are transposases related to the transposase of the canonical piggyBac transposon from the moth， Trichoplusia ni. This family also includes genes in several genomes， including human， that appear to have been derived from the piggyBac transposons. This gene belongs to the subfamily of piggyBac transposable element derived (PGBD) genes. The PGBD proteins appear to be novel， with no obvious relationship to other transposases， or other known protein families. This gene product is specifically expressed in the brain， however， its exact function is not known. Alternative splicing results in multiple t。
